NAME

dcod2lum - Convert hardcopy characteristic curve file to softcopy format

 

SYNOPSIS

dcod2lum in-file out-file

 

DESCRIPTION

Command line program that converts a hardcopy characteristic curve file to softcopy format. In other words, the measured optical density (OD) values from the input file are transformed to the luminance space according to the formula:

  L = La + L0 * 10^(-D)

where L is the resulting luminance, La is the reflected ambient light and L0 the illumination (both measured in cd/m^2), 'D' the optical density (OD). Please note that if no illumination value is specified in the input file (keyword lum) all optical density values are mapped to a constant luminance.  

PARAMETERS

in-file   hardcopy characteristic curve file to be converted

out-file  softcopy characteristic curve file to be written

 

NOTES

The format of both input and output file is described the documentation of the dcmdspfn command line tool. In addition, the data folder contains sample characteristics file monitors, cameras, printers and scanners.  

FILES

<datadir>/camera.lut - sample characteristics file of a camera
<datadir>/monitor.lut - sample characteristics file of a monitor
<datadir>/printer.lut - sample characteristics file of a printer
<datadir>/scanner.lut - sample characteristics file of a scanner
